What is it?

MiEx is a world exporter for Minecraft and Hytale, written in Java. It converts blocks in a world into USD (Universal Scene Description) files, so the environment can be used as a set in 3D animation and rendering tools. It was originally built by Bram Stout Productions to create sets for animations.

The exporter uses the game's resource pack system to produce models and textures, and it can work with custom resource packs and modded worlds. It supports Minecraft Java Edition 1.2.1 and later, Minecraft Bedrock Edition 1.17 and later, and Hytale worlds, resource packs and mods. Output is split into export chunks that can be loaded selectively in a scene, and a level-of-detail system reduces polygon counts in distant areas.

Other options include face merging, cave removal, foreground and background separation, texture atlases, animated textures, biome colour blending, CTM connected textures, and a modifier system for per-block or per-face changes. The project is distributed as a standalone JAR file.
